Article Summary
Vaultody has expanded its institutional digital asset infrastructure with native support for four leading EVM networks: Arbitrum, Optimism, Base and Avalanche C‑Chain. These integrations give exchanges, banks, funds and fintechs access to higher throughput, significantly lower transaction costs and full smart contract capabilities, all governed through Vaultody’s MPC-based General, Automation and Smart Vaults. Clients can consolidate operations under a single, policy-driven platform while using the same address across supported EVM chains and centralising gas fees to reduce operational complexity.
Why These Four EVM Chains Matter for Institutions
In only a few years, Arbitrum, Optimism, Base and Avalanche C‑Chain have become core infrastructure for Ethereum-native applications and institutional deployments. They are all compatible with the Ethereum Virtual Machine (EVM), which allows existing Ethereum smart contracts and dApps to be deployed with minimal or no code changes.
Vaultody prioritised these protocols because they deliver a common set of benefits that are particularly valuable for high-volume, risk-aware organisations:
- Scalability: Each network increases transaction throughput and reduces congestion on Ethereum or within the Avalanche ecosystem, enabling smoother execution for trading, payments and on-chain operations.
- Lower fees: Typical transaction fees on these chains are significantly lower than on the Ethereum mainnet, making them well-suited for frequent transactions, micro‑settlements and complex DeFi activity.
- Smart contract support: All four support full smart contract functionality, allowing institutional users to interact with DeFi protocols, tokenised assets and custom on-chain logic.
- EVM compatibility: Because they are EVM-compatible, existing Ethereum tooling, wallets and integrations can be reused, shortening deployment times and reducing engineering overhead.
Arbitrum: Optimistic Rollups for Higher Throughput
Arbitrum is a Layer‑2 scaling solution for Ethereum that went live in 2021. It uses optimistic rollup technology to move most computation and data storage off-chain while still inheriting Ethereum’s base-layer security.
Transactions are executed on Arbitrum, aggregated into batches and then posted to Ethereum as a single compressed data set. Under normal conditions, these batches are accepted as valid, but they can be challenged via fraud proofs if necessary. This design results in:
- Substantially higher throughput compared to the Ethereum mainnet.
- Lower transaction fees for users and applications.
- A growing ecosystem of DeFi, NFT and infrastructure projects that run on top of Arbitrum.
For Vaultody clients, Arbitrum provides a cost-efficient environment for activities such as exchange deposits and withdrawals, market making flows, and DeFi strategies, all managed under institution-grade governance.
Base: Coinbase’s Layer‑2 for Scalable dApps
Base is a Layer‑2 rollup launched by Coinbase in early 2023. Built on the Optimism OP Stack, Base is designed to host decentralised applications while using Ethereum as its settlement and security layer.
Like other optimistic rollups, Base processes most transactions off-chain, compresses them and submits proofs back to Ethereum. In practice, this delivers:
- Lower gas costs relative to Ethereum mainnet.
- Improved execution speed and shorter settlement times.
- Seamless access for Coinbase users and products, which many institutions already rely on for liquidity and fiat on‑ramps.
When combined with Vaultody, Base becomes a scalable extension of existing Ethereum operations. Institutions can interact with Base-based dApps, tokenised assets and payment flows while retaining the same MPC security, approval policies and audit trails used for other networks.
Optimism: A Mature Layer‑2 Ecosystem
Optimism is one of the earliest production-ready Ethereum Layer‑2 networks, active since 2020. It also uses optimistic rollups to reduce gas costs and boost throughput while keeping Ethereum as the ultimate source of security.
Key elements of the Optimism ecosystem include:
- Optimistic rollups: Off-chain execution with batched settlement on Ethereum, enabling faster and cheaper transactions.
- Fault proofs: Mechanisms that allow participants to challenge invalid state updates in rollup batches, preserving trustlessness.
- OP Stack: An open-source framework adopted by multiple projects, including Base, for building L2 chains with shared tooling.
- Superchain vision: The concept of a network of interconnected OP Stack chains, designed to improve cross‑chain user experience and liquidity.
By supporting Optimism inside Vaultody, institutional users can treat Optimism as a natural extension of their Ethereum strategy, with consistent wallet governance, multi‑sig policies and MPC protection.
Avalanche C‑Chain: High-Performance EVM Layer‑1
Avalanche C‑Chain (Contract Chain) is the EVM-compatible smart contract chain within the Avalanche network, which also includes the X‑Chain and P‑Chain. Launched in 2020, it is a Layer‑1 blockchain rather than a rollup, and uses the Avalanche consensus protocol, which blends aspects of classical and Nakamoto consensus.
The C‑Chain is designed to offer:
- Fast finality and high throughput, suitable for trading and real-time applications.
- Lower average fees compared to Ethereum mainnet.
- Full EVM compatibility, facilitating straightforward migration of Ethereum dApps and tooling.
- Horizontal scalability via Avalanche subnets, which can host additional custom chains without overloading the primary network.
Within Vaultody, Avalanche C‑Chain can be used for cost‑efficient settlement, DeFi strategies and tokenised asset operations, while being governed by the same MPC and policy framework as other supported chains.
Using the New Integrations Inside Vaultody
The new networks are available across all three of Vaultody’s core vault types, allowing institutions to integrate them into existing operational flows without re‑architecting their control framework.
1. Reduce Network Fees with Smart and Automation Vaults
By shifting appropriate flows from Ethereum mainnet to Arbitrum, Optimism, Base or Avalanche C‑Chain, institutions can substantially reduce per‑transaction costs. Vaultody’s Automation Vaults let teams codify fee‑sensitive workflows, such as:
- Recurring payouts to partners or customers.
- Market‑making or arbitrage strategies that demand low friction.
- Periodic treasury rebalancing across exchanges and on-chain venues.
The “station address” feature allows you to centralise gas funding for selected networks in one place, helping to eliminate wallet dust and avoid fragmented gas balances across many addresses.
2. Create and Control Transactions Manually or Automatically
Teams can execute transactions in two ways:
- Manual execution: Operators initiate transfers directly from General, Smart or Automation Vaults, subject to the organisation’s approval policies.
- Automated execution: Predefined rules in Automation Vaults can trigger network‑specific actions, such as moving idle balances to yield strategies or performing periodic consolidations on Arbitrum, Optimism, Base or Avalanche C‑Chain.
3. Use the Same Address Across All Supported EVM Chains
Vaultody supports a unified address concept for EVM-compatible networks. The same address can be used across Ethereum, Arbitrum, Optimism, Base, Avalanche C‑Chain and other supported chains. This reduces the risk of human error when copying or verifying addresses and simplifies reconciliation and compliance reporting.
4. Manage Smart Contract Funds Safely with Smart Vaults
Smart Vaults are specifically designed for workflows that involve smart contracts, including DeFi protocols, tokenised assets and bespoke institutional agreements. When combined with the new EVM networks, Smart Vaults enable you to:
- Route funds into and out of contracts on Arbitrum, Optimism, Base or Avalanche C‑Chain under strict approval rules.
- Segregate high‑risk or experimental activities from core treasury operations.
- Leverage Vaultody’s MPC engine so that no single party ever holds a complete private key.
These capabilities make the newly integrated chains immediately usable for production‑grade, policy‑driven operations rather than one‑off experiments.
What This Upgrade Means for Institutional Users
By onboarding Arbitrum, Optimism, Base and Avalanche C‑Chain, Vaultody is extending its role as a control layer for multi‑chain institutional activity. Organisations can combine:
- The scalability and low fees of modern EVM networks.
- The MPC security, segregation of duties and auditability required by regulators and internal risk teams.
- The operational convenience of unified EVM addresses and centralised gas management.
This alignment between technical performance and governance makes it easier for institutions to experiment with new protocols, expand product offerings and adjust to market conditions without compromising on security or internal controls.
Vaultody will continue to add new blockchains and features in line with institutional requirements, and future updates will be shared through the company’s blog and documentation.
